Automated summary

This article compares and analyzes digital transmitters based on resource usage. It finds that one type of all-digital transmitter has lower resource consumption compared to other research. However, in terms of frequency agility, this method has a smaller frequency range compared to another implementation with only 12 MHz bandwidth, which implies the work is more concentrated, but the performance metrics of digital transmitters cannot fully justify it.
